SummerGuide 20L+
SummerGuide 20L+ is a collaboration backpack designed with Swiss mountain guides from BERGSCHAFT. Designed specifically for demanding summer alpine tours, this backpack combines durability and functionality to meet the rigorous standards of professional guides.
Crafted from tough Ultra200X fabric, with Ultra400X reinforcement at the bottom, it ensures long-lasting resilience. The design includes shoulder strap pockets—one for small essentials like a phone, and another for a soft bottle—plus an external zippered pocket and two internal compartments: one for keys and wallet, and the other sized for a SAM splint. The back panel is made of EcoPak EPLX450RS with thick EVA foam which can be removed in case of emergency bivouac. The 25mm webbing hip belt is also removable, secured with a durable aluminum triglide. The roll top has magnetic closure for easy alignment and top lid rope carry strap is removable as well.
